         3 . The control apparatus according to  claim 2 , wherein
 in a case where authentication information inputted to a screen of the tab in the locked state matches authentication information that is set in advance to the screen of the tab in the locked state, the locking control is performed to set the menu screen of the tab to an unlocked state from the locked state.   
     
     
         4 . The control apparatus according to  claim 3 , wherein
 in a case where the tab in the locked state is set to the unlocked state, the displaying displays the menu screen corresponding to the tab that was in the locked state.   
     
     
         5 . The control apparatus according to  claim 1 , wherein
 based on that the backlight of the display is put in the off state, the locking control is performed to set all the menu screens of tabs in which the lock setting is effective that are displayed on the display screen to the locked state.   
     
     
         6 . The control apparatus according to  claim 1 , wherein
 the backlight is turned on in a case where the display screen is displayed and is turned off in a case where a predetermined period of time passes after no operation by a user on the display is detected.   
     
     
         7 . The control apparatus according to  claim 1 , wherein
 a case where the condition that the backlight of the display is put in the off state is satisfied is that a predetermined period of time passes after no operation by a user on the display is detected.   
     
     
         8 . A method of controlling a control apparatus, comprising:
 while it is possible to display on a display a display screen in a form of tabs including a plurality of tabs and a plurality of menu screens corresponding to the plurality of tabs, respectively, displaying on the display a display screen including a menu screen corresponding to a predetermined tab in accordance with selection of the predetermined tab on the display screen;   setting a menu screen corresponding to at least one tab out of the plurality of menu screens corresponding to the plurality of tabs to a locked state in which the menu screen is not displayed; and   setting whether to make lock setting effective or ineffective, wherein   in a case where a condition that a backlight of the display is put in an off state is satisfied, based on that lock setting of a menu screen corresponding to a current tab that is displayed last before the backlight is put in the off state is set to effective, the menu screen corresponding to the current tab is set to the locked state.   
     
     
         9 . A non-transitory computer readable storage medium storing a program which functions in a control apparatus and causes the control apparatus to:
 display on a display a display screen in a form of tabs including a plurality of tabs and a plurality of menu screens corresponding to the plurality of tabs, respectively, and display on the display a display screen including a menu screen corresponding to a predetermined tab in accordance with selection of the predetermined tab on the display screen;   perform locking control to set a menu screen corresponding to at least one tab out of the plurality of menu screens corresponding to the plurality of tabs to locked state in which the menu screen is not displayed; and   set for each menu screen corresponding to the tab whether to make lock setting to set the menu screen corresponding to the tab to the locked state effective, wherein   in a case where a condition that a backlight of the display is put in an off state is satisfied, based on that lock setting of a menu screen corresponding to a current tab that is displayed last before the backlight is put in the off state is set to effective, the locking control is performed to set the menu screen corresponding to the current tab to the locked state.
